A High-Frequency Longitudinal-Torsion Composite Vibration Sponge Drilling Workbench and Its Application

Abstract

The invention relates to a high-frequency longitudinal torsion composite vibration sponge punching workbench and an application thereof. The workbench comprises a base, a horizontal movement mechanism, a fixing frame, a vertical movement mechanism, a supporting frame and a high-frequency longitudinal torsion composite vibration sponge punching device. The high-frequency longitudinal torsion composite vibration sponge punching device comprises an ultrasonic generator, an ultrasonic transducer, at least one stage of amplitude-change pole and a tubular tool. The tubular tool comprises a connector connected with the amplitude-change poles, a tube body with a cavity inside and a cutting edge, wherein one end of the tube body is in threaded connection with the connector; the cutting edge is arranged at the other end of the tube body; and the tube body is provided with a longitudinal torsion composite vibration conversion structure. According to the technical scheme, sponges are punched easily in a high-frequency longitudinal torsion composite vibration mode; horizontal movement of workpieces to be machined is achieved through a horizontal movement mechanism; the punching device can move up and down accurately through the vertical movement mechanism; and by means of the fixing frame, accurate automatic-control punching can be conducted in the specific positions of the workpieces to be machined as needed.

Description

Technical field [0001] The invention belongs to transfer roller processing equipment, and particularly relates to a high-frequency longitudinal torsion composite vibrating sponge punching workbench. Background technique [0002] The transfer roller of a printer or copier generally includes a metal mandrel and an elastomer layer sheathed outside the metal mandrel. The elastomer layer is usually the above-mentioned elastic material. In order to set the inner mandrel, a hole needs to be opened in the elastic material. . The transfer roller is the core component of a printer or a copier, and requires very high dimensional accuracy and flatness of the shape. [0003] Currently, the following two methods can be considered for drilling holes in the sponge. One is to use tool drilling. For example, the above technical solution is disclosed in Chinese patent CN201856270U. However, under the action of a rotating tool, it will be axially subjected to horizontal and torsional forces, resultin...
